PYSEC-2026-542 smolagents has Sandbox Escape Vulnerability in the local_python_executor.py Module

A sandbox escape vulnerability was identified in huggingface/smolagents version 1.14.0, allowing attackers to bypass the restricted execution environment and achieve remote code execution RCE. The vulnerability stems from the localpythonexecutor.py module, which inadequately restricts Python code...

CVE-2026-41523

A flaw was found in vLLM, an inference and serving engine for large language models LLMs. An unauthenticated attacker can exploit an assert-based security check during activation function loading. By publishing a malicious HuggingFace model, an attacker can achieve arbitrary code execution on the...

Out Of Band Data Exfiltration

Claude Code is vulnerable to Out-of-Band Data Exfiltration. The vulnerability is due to the pre-approval of the hostname huggingface.co as a bare hostname for the WebFetch tool, where any path on that domain—including attacker-controlled model repositories—was auto-approved without a permission...
